Although this combination had been self-evident in the past, the needs of each diverged towards the end of the twentieth century, when the conveyance of parcels was progressively separated from public transportation.
This split became official with the conversion of PostAuto into a separate subsidiary of the Swiss Post in February 2005.
The buses operated by PostAuto are a Swiss icon, with a distinctive yellow livery and three-tone horn.
Services are provided by PostAuto Switzerland, a subsidiary company of Swiss Post with its headquarters in Bern.
The company is responsible for 869 bus routes with 2,193 buses in Switzerland, transporting over 140 million passengers annually on its 11,869 km (7,375 mi) long network.
